Yes, that's required for built as well. For example, with the Android
integration, I created a preference for the root location for the SDK
install. Under there all the tools are in a well known path and passed
to the environment when running the build and now when running the
debugger. That should be sufficient.

This is essentially what the CDebugger extension is. I did this for
the MinGW debugger where I automatically put the full path to the
debugger in place when the user selected that debugger.

I guess what I am really thinking about is a CDebugger type thing,
possibly more focused on launching than the actual debugger interface.
And maybe even focused exclusively on gdb. The cases I'm seeing is
really just the need to run commands at start up in a certain order as
well as launching the right gdb executable.

Let's give it some thought and I can spend a little time on it once
I'm back from holidays which end this week.

Thanks Marc,
